Hi, Please forgive me if I am asking a basic question. I want to pick random number from the set {2,3}. It should either pick 2 or 3 randomly. I have been looking at these functions called 'rand', 'randi', 'randperm' etc., but i couldn't figure out how to use them for my problem. Any help would be appreciated.

Thanks a lot Azzi. By the way, what is the probability to chose one of these numbers?
